Answer 2

The chemical equation you provided is not balanced. Let's balance it:

H₂O₂ + H₂S → H₂SO₄ + H₂O

To balance this equation, follow these steps:

1. Count the number of atoms of each element on both sides:

Left side:

• Hydrogen (H): 2 (from H₂O₂) + 2 (from H₂S) = 4 atoms
• Oxygen (O): 2 (from H₂O₂)
• Sulfur (S): 1 (from H₂S)

Right side:

• Hydrogen (H): 2 (from H₂SO₄) + 2 (from H₂O) = 4 atoms
• Oxygen (O): 4 (from H₂SO₄) + 1 (from H₂O) = 5 atoms
• Sulfur (S): 1 (from H₂SO₄)

2. Balance the elements one at a time. Start with sulfur:

Balance sulfur by putting a coefficient of 1 in front of H₂SO₄ on the right side:

H₂O₂ + H₂S → H₂SO₄ + H₂O

3. Balance hydrogen atoms:

Balance hydrogen atoms by putting a coefficient of 2 in front of H₂O on the right side:

H₂O₂ + H₂S → H₂SO₄ + 2H₂O

4. Balance oxygen atoms:

Now, balance oxygen atoms. There are 2 oxygen atoms in H₂O₂ and 5 in H₂SO₄ and H₂O, so there are 7 oxygen atoms on the right side. To balance this, put a coefficient of 7/2 (or 3.5) in front of H₂O₂ on the left side:

3.5 H₂O₂ + H₂S → H₂SO₄ + 2H₂O

This equation is now balanced.
